Flannel shirts might not seem like the height of style, but with some knowledge, they can be one of your wardrobe’s most versatile items throughout the fall and winter. When the temperature drops or you decide to take a trip to the mountains, a flannel shirt seems like an absolute need. Sure, some fashions, like a red and black buffalo check, have a lumberjack feel to them, but who else has worn a flannel successfully? In other words, adding a few variations of the heavyweight button-down to your wardrobe is highly recommended. The best costume combinations amid the pinnacle of Y2K nostalgia, if anything, are those that touch on the ’90s and ’00s fashion.
